阅读理解The financial climate for charities is worsening, with more than half hit by the economic downturn, a survey reveals today. Over half of those affected report a decline in income triggered by the recession at a time when one fifth of charities are seeing an increase in demand for their services. Despite the success of Comic Relief, which raised £60m for anti-poverty charity projects last weekend, the overall financial picture for the voluntary sector is gloomier than it was six months ago, says the Charity Commission report.Dame Suzi Leather, the Chairwoman of the Charity Commission, said, “Clearly the impact of the financial downturn on charities is widening and deepening. Some charities still face that double chances of a drop in income as well as an increased demand for services. The research tells us that the number of charities taking steps to reduce the risks that the financial downturn brings has risen since we conducted our first research. However, not all charities are putting measures in place to protect their work and their funds. It is very surprising that more charities are not considering collaboration with others, as this can help them share expertise and costs.”In September the commission found that 38% of charities had been affected by the downturn, with 16% describing the impact had been “very significant or significant.” The latest report shows those proportions have increased, to 58% and 25% respectively. Bigger charities — those with an annual income of more than £ 1 million — were less likely to have been hit by income reductions. But almost two-thirds of that group were concerned that the downturn would affect their work in future.The commission surveyed a random sample of 1,000 charities of varying sizes in England and Wales during January and February. It found the collapse in the value of stocks and shares — for many charities the single most important source of income — has impacted hard on the sector, which is also hurting from a falloff in corporate donations and private legacies.Charities that delivered services overseas reported they had been badly affected by the fall in the value of sterling. The survey suggests there is little sign that charities overall are preparing to make big cutbacks in jobs or capital investments. Only a tiny proportion of those surveyed said they were facing problems meeting pension commitments. (1) According to the passage, the proportion of charities suffered from income reduction is ___.
